Harmonic ElectraTM XT Xtream (formerly known as ViBE® XT1000) is a high-density encoder that offers the highest real-time transcoding density and supports any format conversion on the market. It significantly reduces procurement and operational costs and shortens time-to-market for operators facing channel growth and increasing multi-screen applications.
Digital television distribution is changing faster than ever, with a growing number of broadcast programs and an increasing variety of formats emerging to support the explosive growth of multi-screen devices, including tablets, smartphones, and connected TVs. Service providers must confront these challenges while continuing to increase subscriber numbers, develop new IPTV services, and maintain average revenue per user. Harmonic Electra XT helps operators successfully address this dilemma.
The cost-effective Electra XT provides high-density and scalable real-time transcoding for traditional cable TV, IPTV, DTH, DTTV, and multi-screen applications.
Supports any format conversion
Electra XT receives compressed video via IP streams and can transcode audio and video between any formats. For video, the device supports standard definition and high definition MPEG-2 and MPEG-4 AVC. It also supports various audio codec formats, including MPEG-1 Layer II, Dolby® Digital (AC-3), Dolby Digital Plus (E-AC-3), AAC-LC, and HE-AAC v1/v2 in mono, stereo, and surround sound modes.
Unmatched density and scalability
Electra XT leverages years of extensive experience and innovative technology in video compression algorithms to deliver the industry's best transcoding density, supporting up to 180 SD or 54 HD channels within 2 RU. The design incorporates high efficiency and a modular architecture that supports operators' business growth, accommodating up to 9 hot-swappable audio/video processing modules. Each module supports 20 standard definition or 6 high definition channels (or a mix) through per-channel software licensing.
The high-density features of the transcoder significantly reduce the required rack space and lower energy consumption. The flexible web graphical user interface facilitates the simultaneous configuration and monitoring of hundreds of encoding channels.
More than just encoding
Electra XT is more than just a basic high-density encoder. To add value to workflows, the device includes efficient advanced features such as user-defined text and logo insertion, as well as manual and automatic volume adjustments on transcoded audio channels.
For satellite, terrestrial, and cable applications, the Electra XT supports internal statistical multiplexing to meet end-user video quality requirements while optimizing bandwidth. For multi-screen applications, the device supports adaptive bitrate encoding. Video can be transmitted to an external packager or internally scrambled and packaged in Apple® HLS, Microsoft® Smooth Streaming, and MPEG-DASH formats.
